CRUSHER-PLATE.

SPECIFICATION forming part of Letters Patent No. 624,589, dated May 9, 1899.

Applicationfiled September 14, 1897. Serial No. 651,692. (No model.)

To all whom, it may concern:

Be it known that I, HENRY J. WESSINGER, of Tower, St. Louis county, Minnesota, have invented certain Improvements in Crusher- Plates, of which the following is a specification.

My invention relates to improvements in crusher-plates for use in stone and ore crushing machines, its objccbbeing to provide a sectional plate, the worn parts of which can beremoved and others substituted without the discarding of the entire plate.

The ordinary crusher-plate wears only at each end and therefore becomes unfit for further use, while the body of the plate is still in good condition, and to obviate this objection my invention is particularly designed.

To this end my invention consists in forming the plate of a number of sections detach ably secured together by links, so as to make a firm plate, but which will allow the removal of the worn sections and the substitution of perfect ones.

My invention further consists in the specific construction hereinafter more particularly described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan view of my improved crusher-plate. Fig. 2 is a side elevation of the same; and Fig. 3 is a side elevation of the jaw forming part of the crushing-machine, showing the plate in place ready for use.

In the drawings the crusher-plate A is shown made up of a number of similar sections B. The meeting ends of these sections are each provided with a U-shaped channel 2, forming a lug 3. When the sections are arranged in place, as shown in the drawings, the lugs 3 abut against each other and are surrounded by links 4, connecting the sections together, the links lying entirely within the channels 2.

In use the plate, made up of sections, is secured in place in suitable manner, as in Fig.

3, in which the jaw O is provided with a recess 5 to receive the plate and is formed with an overhanging lip 6,adapted to fit into a corresponding notch 7 in the end of the abutting plate-section, the section forming the opposite end of the plate being held bya tapering wedge 8 passing through the jaw-a-nd se cured by a suitable nut 9. As the end sections become worn they may be removed and perfect ones substituted therefor, thus prolonging the life of the plate.

It will be evident that my plate is an improvement over other known forms in that the sections are not only locked to a base or jaw, but are also interlocked. The interlocking of the plate-sections prevents the workin g loose of any of the sections or any move ment between them-in fact, constitutes of the series of sections apractically rigid plate, while at the same time permitting the sections to be taken apart and a worn plate replaced by a new one.

1. In combination with the recessed jawof a stone crusher, the sectional plate fitted thereto, and the means carried by said jaw and adapted to interlock with any one of said sections, whereby the same may be interchanged as desired.

2. In combination with the jaw of a stone crusher, a wear-plate made up of a series of sections, means for detachably connecting said sections to each other, and interlocking connection between said jaw and plate, consisting of a projection carried by one, and adapted to fit into a notch in the other, said sections being similarly formed so as to be interchangeable.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY J. WESSINGER.
